I've always been an advocate of consumer generated advertising networks such as these - regardless of how little search engines want you to use them or how often many experts tell everyone to avoid them. People still use them (and frequently) so it might be something you should investigate if you have the budget to do so. The service looks similar to others on the surface. The only real differentiating factor that I could find was that the transaction fee for advertisers is 20%, whereas other networks could charrge upwwards of 30-35%.

"This website is focused on improving the quality of content for

PayingPost. "We have introduced a variety of features that will allow
our service to naturally improve itself and provide the best Web 2.0
advertising experience for both bloggers and advertisers."
